660r cold blooded?

I have a raptor 660. It is jetted at stage 2, yoshima exhaust, kn air filter. It had ben having idle problems so i removed the parking brake. I bought a new battery last week and it started right up. Now it is not wanting to turn over. Im not sure if it is due to the coldness or if its the carbs that need cleaning. I have not tried to jump it yet because i dont know if that will blow the battery up. Any suggestions? Also i have no idea how to take the carbs out

Short and long race Raptor has Duals and jetted also k&n airfilter an Programer. Ltr some kinda exhaust and jetted. Which wins ?
